Polar Magnet Pen & Stylus
Crowdfunded projects pose a degree of risk for buyers, so be sure to do your research and fully read the seller's detailed description and production plans before plunking down your hard-earned money.
Andrew Gardner invented a pen and stylus combo with a body made of 12 small cylindrical magnets. Use its body as you would any other magnet or just play around with it. The pen is compatible with 0.3mm gel ink cartridges.
